IMPROVEMENT IN GANG CHEESE-PRESSES.

Specification forming part of Lett-ers Patent No. 222,72/l, datedDecember 16, 1879; applicaiiop filed May 20, 1879.

To all whom it 'may concern.-

Be it known that I, JAMES NAYLOR, Jr., of Rochester, in the county ofMonroe and State of New York, have invented certain new and usef'ulImpmvements in Gang'CheesePresses g and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to an improvement in that class of cheese-pressesknown by the general term of gang-presses,7 in which several cheeses maybe placed at the sa-me time, and all acted upon by the same mechanism,giving an equal pressure to each cheese in the press, whatever numberthere may be, the object bel ing to furnish a cheaply-constructed press,in

which the operation of pressing cheeses may be performed in less timeand with less labor than with the gang-presses in common use, which aregenerally operated by a screw, the turning of which, in drawing back thefollower, as well as in forcing it up, is slow, although the powerexerted by such a press when properly constructed is fully sufiicientfor the purpose named. In order to avoid this loss of time in operatingthe press, and the excessive cost of construction, I haveinvented thehereinaftendescribed press, which consists, essentially, in soconstructing and arranging the parts of the press as to dispenseentirely with the screw, substituting therefor one or more toothedracks, secured to or formedin the bed of the machine, in which workpawls attached to the arm of a rock-shaft carried in suitablejournal-bearings upon the movable follower of the press, said rock-shaftbeing oscillated by a lever attached thereto, and the follower preventedfrom having a retrograde movement by a shaft provided with pawlscatching in the teeth of the racks, as will be hereinafter fully setforth, and then specifically stated in the claims.

In the drawings, Figure 1 is a plan of the press, showing thearrangement of the bed with its racks, the follower, and thc rock-shaftand pawls, by which motion is given to the follower. Fig. 2 is alongitudinal section on the line x a' of Fig. 1, giving a side view ofthe operating' parts. Fig. 3 is a transverse section of the press in therear of the follower, and shows the relative positions of the follower,bed, and rock-shaft in a vertical plane.

The .side pieces, A, of the frame are preferably constructed of wood,and are united at their ends by the cross-pieces A', one of which, inconnection with the side pieces, A, supports the stationary cross-headB, it being securely bolted'to the parts named, so as to be immovableunder the great strain to which it will be subjected when the press isin operation.

A tight bottom, B, is securely fastened to the under side of the frame,thus forming a tank or cistern, which catches the whey asit runs fromthe cheeses, and which may be drawn off whenever needed by a cock orplug, a, placed in the lowest part of the bottom.

Two `or more ways, b, are secured to the bot tom B', and extend nearlythe whole length ot'- the cistern, sufficient room, however, b'eing leftat one end for the passage of the whey, so that the cistern may beeasily and fully drained.

These ways serve as a support for the cheese hoops, which are soconstructed as to4 have a level bearing on them to bring their axisparallel with the longitudinal axis of the press, thus causing theforward motion of the movable follower to act equally upon the contentsof all the hoops in the series operated upon.

Guide-strips c are secured to the side pieces of the frame on theoutside, near their upper edge, and serve as guides to the movablefollower G, the ends of which project over the sides of the press andextend rearward, forniing the sliding side pieces, d, which hook nnderthe strips c, and prevent any swaying or unequal movement of the endsofthe follower. Journaled in these sidevpieces, d, is a rock shaft, D,provided with arms c, in which are pivoted the pawls c'. A lever, c', isalso rmly secured to the rock-shaft in such aposition that when thrownback against the follower, as shown by dotted lines in Fig. 2, it shallraise Y cheeses in the hoops between the follower and stationarycross-head B.

In order to prevent any reaction of the follower when the lever c israised to get the pawls ein position for another forward move- 1 ment, ashaft, E, is journaled in the movable side pieces, d, near their rearends. Into this shaftare inserted the pawls a', moving withthe shaft, sothat they may be lifted out of con-tact f with `the racks by turning theshaft; but when resting upon the racks thesc -pawls catch automatically,and hold the lfollower at any point to which it may have been forced bythe action of the rock-shaft D and pawls e.

The operation of this press will be perfectly clear from the foregoingdescription, audits simplicity of construction and e'ectiveness will, it,is believed, render it a favorite .with

both dairymen, and manufacturers.

I am aware that presses have been heretofore constructed in which themovement of the follower was produced bythe action of pawls upon a rack5 but so far as my knowledge eX- tends none of them have accomplishedthe desired result with such a simple array of mechanisiuas is kused inthis press.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent, the following: v

1. In a gang cheese-press, the combination of the movable follower,provided with a rockshaft and pawls pivotally attached to the armsthereof, with the racksd, or their equivalents, substantiallyassetforth.

2. In a gang cheese-press, the follower provided with the guided sidepieces, d, in combination with the rock-shaft D, its actuatinglever andpawls, and the pawl-shaft E, all operatin g substantially as specified.

3. The side pieces, A, provided with racks d, and the cross-head B, incombination with the movable follower C and its operative mechanism,constructed and arranged substantially as shown and described.

at. 'In ya vgang cheese-press, the mean-s, hereinbefore described, .forimparting :a forward movement to the follower, consistingv-essentially-of atoggle-actingpawl and toothed rack, as set forth.

5. In a gangicheese-press, lthe 'toggle-acting pawl and lever forfproducing aforward movement of .the follower, .in combination -with theindependent pawl-shaft andits pawls, for preventing a retrogrademovement of the same, substantiallyas described.

In testimony that I claim the 'foregoing I have .hereunto set `my handthis 13th `day of May, 1879.
